Smaller mobile devices may be charged by connecting the mobile device toa p ower source via wires. However, due to size-concerns, smaller mobiledevices may lack the requisite space to Incorporate the components forwired charging. Additionally, due to their size, owners are less likelyto remove the devices from their housing or usual storage or wearablelocation. Accordingly, smaller mobile devices have a number of problemsarising out of their ability to b charged.

As a solution to these problems, smaller mobile devices may be housed inproximity to larger mobile devices. Accordingly, the smaller mobiledevice may be inductively charged by the larger device. Additionally,when a first mobile device and a second mobile device communicatewirelessly via a Bluetooth BLE, NFC, or other wireless connection, thesewireless channels may be utilized to maximize charging capabilitiesbetween the first and second mobile devices. These and other technicalimprovements may exist.

FIG. 2 depicts an example electronic transaction card 200. As shown inFIG. 2, electronic transaction card 200 may include a top output layer202. The top output layer may be a film covering, a plastic covering,and/or the like. The top output layer 202 may be constructed ofscratch-resistant and/or scratch-proof materials. Materials that may beused as a top outer layer 202 may include polyvinyl chloride (PVC),polylactic acid (PLA), acrylonitrile butadiene styrene (ABS),polyethylene terephthalate (PET), Polyethylene terephthalateglycol-modified (PET-G), polyester film or plastic sheet (e.g., Mylar),polycarbonate (PC), and/or the like. An electronic transaction card 200may further include a top protective layer 204, such as a clearscratch-resistant coating and/or scratch-proof material to protect theunderlying components. For example, various scratch-resistant materialsinclude materials coated with a scratch resistant chemical coating, suchas a UV curable chemical coating. Scratch-proof materials may include amineral glass, a sapphire glass, thin film alloys, ITO, ZnO, PVC, PET,BoPET (e.g., Mylar), polyvinylidene fluoride (e.g., Kynar),polyvinylidene difluoride, PC and/or PET-G.

An electronic transaction card may include a potting 206 or filler epoxyaround the electrical components to provide strength and/or waterresistance. A potting 206 may include a light guide, which may beconstructed of optical grade materials such as acrylic, resin,polycarbonate, epoxies, and/or glass. Potting 206 may also includeinjection molding, such as over molding and/or multi-shot to encapsulatethe components of electronic card 200. For example, injection moldingmay include ABS, thermoplastic elastomers (TPE), thermoplasticvulcanizate (TPV), thermoplastic polyurethane (TPU), PET, polycarbonates(PC), cold lamination of the outer films to the body of the card usingthermoactive adhesives, hot lamination of the outer films to the body ofthe card using thermoactive adhesives, and/or silicone. Electronictransaction card 200 may further include a Java Applet 208 and JavaApplet integration 210. Although a Java Applet 208 is used through thespecification, any other similar type of code application may be used.Moreover, although Java Applet integration 210 is used throughout thisspecification, any type of interface may be used to allow themicrocontroller to interact with the EMV chip. A Java Applet 208 mayinclude code that executes payments, such as payments made using an EMVchip. A Java Applet 208 may include account-provider specific code toexecute display functionality specific to the account provider. JavaApplet integration 210 may include coded interfaces to allow themicrocontroller to interact with the EMV chip 212.

An EMV chip 212 may include a number of contacts that may interact withand/or be connected to a terminal configured to read data stored on aprocessor of an EMV chip 212. During an EMV transaction, applicationcryptograms may be used to send and receive data packets between theelectronic transaction card 200 and a terminal, such as a merchantterminal. For example, data packets may include user authenticationinformation which an acquisition system and/or issuing financialinstitution may use to authenticate electronic transaction card 200during a transaction. Various cryptographic protocols and/or methods maybe used in this data transmission and reception process. Moreover,during a transaction issuing financial institutions and/or acquisitionsystems may return script commands to the EMV chip 212 via a terminal.These script commands and/or data packets may be transmitted betweenparties over a network. Script commands may be used, for example, toblock transactions, change transaction data stored on the EMV chip(e.g., transaction history, account limits, account balance, and/or thelike). Offline data authentication may also take place using, forexample public key cryptography to perform payment data authentication.For example, offline data authentication may use Static DataAuthentication (SDA), Dynamic Data Authentication (DDA), and/or CombinedData Authentication (CDA).

Electronic transaction card 200 may also include one or more sensors 214to receive input. Sensors 214 may include an activation sensor and/or anoperation sensor, which may be combined and/or separate. An activationsensor may activate the electronic transaction card 200 and an operationsensor may instruct the electronic transaction card 200 to perform anaction based on the received input. An activation sensor may require asecurity input, such as a biometric input (e.g., fingerprint, eye scan,voice recognition, and/or the like), input indicative of a paired mobiledevice (e.g., BLE and/or Bluetooth pairing), input indicative of apassword (e.g., a password received via a sensor on the electronictransaction card and/or a password received on a paired mobile device),and/or the like. An operation sensor may change a display 216 based onreceived input, conduct a transaction via, for example an EMV chip 212and/or contactless payment technologies based on received input, attempta pairing of electronic card 200 and a mobile device, and/or the like.

By way of example, a sensor 214 may include a capacitive touch sensor, apiezoelectric sensor, an inductive sensor, load cells, a light sensor, atemperature sensor, a resistive touchscreen, including for example ananalogue matrix real (AMR) sensors, and/or the like. Sensors 214 mayinclude accelerometers and/or photo sensors to detect motion input.Although the sensor 214 is depicted at a particular spot in thetransaction card 200, a sensor 214 may be placed at any portion of thecard to detect, for example, touch, light, heat, energy, and/or thelike. For example, a sensor may be placed around the outer edges of anelectronic transaction card 200 or at any spot within the electronictransaction card 200. Sensor 214 also may include the entire exteriorsurface of electronic transaction card 200.

A display 216 may be provided within the electronic transaction card200. Although the display as shown includes, for example, a dot matrixdisplay, a number of other display options may be included in theelectronic transaction card 200. For example, lighting, such as LEDlighting, OLED lighting, electro luminescent (EL) displays, and/or thelike, may be used as display components. Display components may alsoinclude electronic paper, Mirasol™, TF LCD, Quantum Dot Display, and/orthe like. Where lighting is used, various lighting technologies may beused to create a display that indicates a number of things to acardholder. For example, edge lighting may be used to create a specificvisual component in the display. A number of LED or OLED lights may beused to illuminate various portions of the display in order to outputinformation to a card holder.

By way of example, a display 216 may be illuminated using a particularcolor to relay to the cardholder balance information of an accountassociated with a transaction card, such as an RGB LED matrix paneland/or RGB LED displays. A red light display may indicate that theaccount balance is within a first predetermined dollar amount or a firstpredetermined percentage of the total spending limit, a particularbudget, a particular budget category, and/or the like. A yellow lightdisplay may indicate that the account balance is within a secondpredetermined dollar amount or a second predetermined percentage of thetotal spending limit, a particular budget, a particular budget category,and/or the like. A green light display may indicate that the accountbalance is within a third predetermined dollar amount or a thirdpredetermined percentage of the total spending limit, a particularbudget, a particular budget category, and/or the like. Various colorsand or number of categories may be used to output this information to acardholder. A display 216 may include other display component, such as,for example, LCD technology, ePaper technology (e.g., e-ink), vacuumflorescent display technology, and/or the like.

By way of example, a display 216 may include a number of LED or OLEDlights and/or light pipes that may be lit in a particular pattern toindicate transaction and/or account information. For example, a display216 may include a circle, semicircle, or other shape of LED or OLEDlighting and/or light pips, where the number of lights illuminatedindicates a dollar amount or a percentage of the total spending limit, aparticular budget, a particular budget category, and/or the like.

By way of example, a display 216 may be activated via a sensor 214,which may include any type of sensor describe herein. For example, adisplay may be activated via a touch sensor, where a user is required totap a location on electronic transaction card 200 a specific number oftimes and/or for a specific length of time (e.g., double tap, tripletap, one long tap followed by one short tap, and/or the like). Inresponse to the received sensor input, a display 216 may be activated todisplay particular data, such as data associated with a transactionhistory, account balance, spending limit, budget categories, budgetspending, budget limits, and/or the like. For example, in response to auser double-tapping a sensor point on electronic transaction card 200, anumber of LED or OLEDs may be illuminated to display the percentage of abudget consumed (e.g., if a budget is $10,000 and a user has spent$3,000, then 3 out of 10 LEDs or OLEDs may be illuminated to illustratethat 30% of the $10,000 budget has been consumed).

A display may be altered and/or modified, for example, depending onwhich account or card is selected to be used. For example, whereelectronic transaction card 200 includes a debit account, a first creditaccount, and a second credit account, display components 216 may reflectthe card number, security code, expiration date, and/or other necessarydata indicative of the account (e.g., second credit account) that isbeing used to execute a transaction. A display may be altered and/ormodified when, for example, an electronic transaction card 200 receivesnew card data and/or new account data from an account holder's mobiledevice via a wireless connection. For example, where an account has beenmarked as associated with fraudulent activity, an account holder and/orissuing financial institution may deactivate the card associated withthe account and issue a new card. Accordingly, new card data may betransmitted from the issuing financial institution to, for example, anaccount holder's mobile device via a network, and then from an accountholder's mobile device to electronic transaction card 200 via a wirelessconnection. A display may also be altered and/or modified whenelectronic transaction card 200 activates a new account. For example,when an account holder applies for a new account (e.g., a new creditcard account, a new checking account, and/or the like), if approved, newaccount data may be transmitted to electronic transaction card 200. Newaccount data may be received at an account holder's mobile device froman issuing financial institution via a network (e.g., using a mobileapplication, mobile optimized website, and/or the like). New accountdata may then be transmitted from an account holder's mobile device toelectronic transaction card 200 via a wireless connection (e.g., BLE,RFID, NFC, WiFi, and/or the like) or a contact connection (e.g., using aterminal in contact with an EMV processor and/or other microchip).

As described herein, electronic card 200 may be fully or partiallypre-loaded with account and/or card data. For example, an applet andplaceholder data (or actual data) may be stored within electronictransaction card 200. Accordingly, when an account holder wishes toactivate a new account (e.g., account holder who maintains a firstcredit account may wish to apply for a second credit account), the newaccount data and/or activation signal may be received from an accountholder's mobile device via a wireless connection or a contact connection(e.g., using a terminal in contact with an EMV processor and/or othermicrochip) and a new account and/or card may be activated and able to bedisplayed on electronic transaction card 200.

An electronic transaction card 200 may include a display driver 218 thattranslates instructions from a microcontroller 224 into display imagesto be displayed using display components 216. A display driver 218 mayinclude an integrated circuit (IC), a state machine, and/or the likethat provides an interface function between the display and themicrocontroller 224. A display driver 218 may include memory (e.g., RAM,Flash, ROM, and/or the like) and/or firmware that includes font displaydata.

An electronic transaction card 200 may include firmware 220 and/or abootloader 222. A bootloader 222 may include code to be executed aselectronic transaction card 200 is activated and before any operatingsystem, firmware, or other code is executed on the electronictransaction card 200. A bootloader may be activated via a sensor 214 andenergy storage component 228 of the electronic transaction card 200.Bootloader 222 may be activated and/or load an application and/orprogram upon detection that card 200 has been inserted into a terminal,charger, and/or the like. Bootloader 222 may be activated using only onetechnique described herein, using multiple techniques described herein,and/or using a card holder or card provider selected technique(s)described herein. Bootloader 222 may only be active during a shortinterval after the card 200 powers up. Electronic card 200 may also beactivated using program code that may be flashed directly to amicroprocessor such as microcontroller 224, EMV processor 212, and/orthe like. Electronic card 200 may not use a bootloader 222 but insteadmay cycle between a sleep state and an active state using program codeand/or memory.

An electronic transaction card 200 may include a microcontroller 224 andan antenna 226. Antenna 226 may include, for example, a loop antenna, afractal antenna, and/or the like.

Power management component 230and/or energy storage component 228 may include connections to sensors214 to receive input and activate electronic transaction card 200 (e.g.,motion input, thermal input, manual input, touch input, and/or thelike).

A flexible printed circuit board (PCB) 232 may be included in electronictransaction card 200. A flexible PCB 232 may include a PCB mounted in aflexible plastic substrate, such as for example, a polyimide, polyetherether ketone, and/or a transparent conductive polyester film. A flexiblePCB 232 may be printed, using, for example screen printing, 3D printing,and/or the like, to arrange circuits on a material, such as polyester.Flexible PCB may include electronic components and connections thatpower electronic transaction card 200. Flexible PCB 232 may controland/or provide integration between the components of card 200. Forexample, flexible PCB 232 mechanically supports and electronicallyconnects the electronic components of card 200 using, for example,conductive tracks, pads, and/or other features. PCB 232 may be combinedwith an energy component (e.g., battery component, power component,etc.) as described in Applicant's U.S. application Ser. No. 15/098,935entitled “Dynamic Transaction Card Power Management” field on Apr. 14,2016, published as U.S. Patent Application Publication No. 2016/0308371,which claims the benefit of U.S. Provisional Application No. 62/266,324filed Dec. 11, 2015, the entire content of which are incorporated hereinby reference. A flexible PCB may also provide antenna support. Aflexible printed circuit (FPC) may be used in place of or in conjunctionwith flexible PCB 232. FPC 232 may be fabricated with photolithographictechnology, such as light exposure of a film material laminated tosubstrate and/or conductive layers. FPC 232 may be printed,silkscreened, and/or the like. FPC 232 may be used as a structuralmember for the electronic components of electronic card 200 and/or forthe card system as a whole 200. Electronic transaction card 200 mayinclude a chassis 234 as a frame or supporting structure. Chassis 234may be a mount for a flexible PCB 232 and may be constructed out offlexible or semi-flexible material as well. Chassis 234 may beconstructed out of a number of materials, including but not limited to,PVC, PC, ABS, styrene, polycarbonate, polyester, PET, any material thatis easily molded, deposited, or laser cut (e.g., organic or inorganicmaterial such as paper, plastic, and/or engineered ceramics), and/or thelike. Chassis 234 may be constructed out of a conductive material.Chassis 234 may increase the rigidity of electronic transaction card 200to prevent damage. Chassis 234 may also be used to detect if electronictransaction card 200 is being held by including sensors 214 aroundchassis 234. Where chassis 234 is constructed out of a conductivematerial, a dielectric constant of chassis 234 and/or electronic card200 may be monitored to detect handling of electronic card 200. Achassis 234 may be used to detect the handling of electronic card 200via a strain gauge. Chassis 234 may be included within or separate froma card backing 236. Card backing 236 may include a magnetic stripe thatmay be read using a magnetic stripe reader. A magnetic stripe may storetracks of data that are used to conduct a transaction using anelectronic transaction card 200. The tracks of data may include a firsttrack capable of storing alphanumeric characters as well as symbols(e.g., ?, !, &, #, and/or the like), such as account numbers, accountholder name, expiration data, security data, and/or other account and/orcard related data. The tracks of data may include a second track capableof storing numeric characters such as account numbers, expiration data,security data, and/or other account and/or card related data. The tracksof data may include a third track of data capable of storing numericcharacters such as an account number, a PIN, a country code, a currencycode, an authorization amount, a balance amount, and/or other accountand/or card related data.

A magnetic stripe may be dynamically altered. For example, an electronictransaction card 200 that is paired to a mobile device via, for example,Bluetooth, BLE, RFID, WiFi Direct and/or other wireless technologies,may receive new track data. The new track data may be unformatted,encrypted, encoded, and/or the like when the new track data istransmitted from the mobile device to the electronic transaction card200. Upon receipt of the new track data, the new track data may berouted to a microprocessor, such the processor of EMV chip 212 and/ormicrocontroller 224. EMV chip 212 and/or microcontroller 224 mayconvert, decrypt, and/or decode the received new track data to ensurecompliance with any standards. Once decrypted, decoded, and/orformatted, the new track data may be save on the tracks of the magneticstripe. The magnetic stripe may be deleted and then the new track datamay be recorded onto the tracks. In this manner, track data stored on amagnetic stripe may be altered at any time upon pairing an electronictransaction card 200 with a mobile device.

Card backing 236 may be made of similar material to that of the outputlayer 202 and/or the top protective layer 204. Card backing 236 may bemade out of a plastic material.

Although the components of electronic transaction card 200 areillustrated in a particular fashion, these components may be combinedand or placed throughout an electronic transaction card 200 in anymanner, such as those depicted in, for example, FIG. 3.

For example, FIG. 3 illustrates an electronic transaction card having anoutput layer 302 which may be similar to output layer 202; an outerprotective layer 304 which may be similar to outer protective layer 204;potting 306 which may be similar to potting 206; Java Applets 308 whichmay be similar to Java Applets 208; Java Applet integration 310 whichmay be similar to Java Applet integration 210; an EMV chip 312 which maybe similar to EMV chip 212; a sensor 314 which may be similar to sensor214; display 316 which may be similar to display 216; display driver 318which may be similar to display driver 218; firmware 320 which may besimilar to firmware 220; bootloader 322 which may be similar tobootloader 222; microcontroller 324 which may be similar tomicrocontroller 224; antenna 326 which may be similar to antenna 226;energy storage component 328 which may be similar to energy storagecomponent 228; power management 330 which may be similar to powermanagement 230; a PCB 332 which may be similar to PCB 232; chassis 334which may be similar to chassis 234; and/or card backing 336 which maybe similar to card backing 236.

For example, FIGS. 4 and 5 illustrate example methods of using a firstdevice, such as a smartphone, to wirelessly charge a second device, suchas an electronic transaction card, using a second mobile device, such asa smartphone. The method 400 may start at block 402. At block 404, thefirst device may receive a signal that the first device is connected toa power source. For example, upon connecting a smartphone charger to anoutlet and the smartphone, the smartphone may detect that the smartphoneis connected to a power source and charging (e.g., via the detection ofa voltage signal on a connector pin). This may be overridden via apreferences stored on the first device such that the first device maycharge the second device regardless of the first device being connectedto a power source.

At block 406, in response to the first device receiving a signal that itis connected to a power source, the first device may generate anadvertising packet. An advertising packet may search for nearby deviceswithin a predefined range. An advertising packet may provide a seconddevice within a predefined range with data required to establish awireless connection between the first device and the second device. Atblock 408, the first device may transmit an advertising packet to asecond device.

At block 410, the first device may receive a response from the seconddevice confirming a wireless connection between the two devices. Thewireless connection may be using NFC technologies, Bluetoothtechnologies, and/or BLE technologies as described herein. A connectionconfirmation response may, but need not, include data describing anamount of energy stored on the second device, an optimal frequency forenergy transmission, and the like. For example, an amount of energystored may be relayed by a measurement of energy or a percentage ofenergy storage that is charged or uncharged. A connection confirmationresponse may include data to determine the distance between the firstdevice and the second device and/or between specific components of thefirst device and second device.

At block 412, the first device may generate a broadcast request toactivate a charging application on the first device and/or an outputmanagement component of the first device. The charging application maymanage charging by transmitting frequencies at the frequency received inthe confirmation response. A charging application may maintain seconddevice charging requirements to more optimally charge the second deviceor alter the frequency received in the confirmation response. Forexample, the charging application may maintain distance-frequency datato vary frequency based on the distance between the first and seconddevices. The charging application may store a predefined charge minimumassociated with the second device. For example, the charging applicationmay store an 80% charge minimum so that if the second device is morethan 80% charged, the charging application will delay broadcasting untilthe second device is less than 80% charged. Output management maydetermine which outputs are available for charging.

At block 414, the first device may begin broadcasting to charge thesecond device. Charging may continue for a predefined period of time(e.g., 2 hours, 30 minutes, etc.) or until the second device is chargeto a predefined amount (e.g., 100% charged, 95% charged, etc.). Thebroadcasting may transmit at frequencies determined by the responsepacket, distance-frequency data, and/or the like. The method may end atblock 416.

The method 500 may start at block 502. At block 504 the first device mayreceive charging preferences via an input/output component. For example,a first device user may input charging preferences into a smartphone viaa touch screen that interacts with a charging application on thesmartphone. Charging preferences may include setting a minimum chargepoint at which to start charging a second device. For example, a usermay not wish to charge a second device unless that device is below 50%charged. Charging preferences may include setting a charge start time, acharge end time, and/or a total charge time. For example, a first deviceuser may desire to begin charging a second device no earlier than 7:00p.m. and end charging a second device no later than 5:00 a.m.. A firstdevice user may desire that charging a second device only last 2 hoursat most. Charging preferences may include a preferred mode ofcommunication between a first and second device in order to inductivelycharge the second device. For example, a user may prefer to use NFCtechnologies over BLE, Bluetooth, RFID, or other radio communicationprotocol technologies for charging.

At block 506, the first device may receive a signal that the firstdevice is connected to a power source. For example, upon connecting asmartphone charger to an outlet and the smartphone, the smartphone mayreceive a signal that the smartphone is connected to a power source andcharging.

At block 508, in response to the first device receiving a signal that itis connected to a power source, the first device may generate anadvertising packet. An advertising packet may search for nearby deviceswithin a predefined range. An advertising packet may provide a seconddevice within a predefined range with data required to establish awireless connection between the first device and the second device. Atblock 510, the first device may transmit an advertising packet to asecond device.

At block 512, the first device may receive a response from the seconddevice confirming a wireless connection between the two devices. Thewireless connection may be using NFC technologies, Bluetoothtechnologies, and/or BLE technologies as described herein. A connectionconfirmation response may include data describing an amount of energystored on the second device. For example, an amount of energy stored maybe relayed by a measurement of energy or a percentage of energy storagethat is charged or uncharged. A connection confirmation response mayinclude data to determine the distance between the first device and thesecond device and/or between specific components of the first device andsecond device.

At block 514, the first device may generate a broadcast request toactivate a charging application on the first device and/or an outputmanagement component of the first device. A charging application maymaintain second device charging requirements to optimally charge thesecond device. For example, the charging application may maintaindistance-frequency data to vary frequency based on the distance betweenthe first and second devices. The charging application may store a userpreferences as described above. Using the data in the response from thesecond device, the user preferences, and/or the charging requirements, afirst device may generate a broadcast request. Output management maydetermine which outputs are available for charging.

At block 516, the first device may begin broadcasting to charge thesecond device. Charging may continue based on user preferences or devicerequirements stored in the first device. The method may end at block518.

For example, as an aid tounderstanding, the following appended claims may contain usage of theintroductory phrases “at least one” and “one or more” to introduce claimrecitations. However, the use of such phrases should not be construed toimply that the introduction of a claim recitation by the indefinitearticles “a” or “an” limits any particular claim containing suchintroduced claim recitation to embodiments containing only one suchrecitation, even when the same claim includes the introductory phrases“one or more” or “at least one” and indefinite articles such as “a” or“an” (e.g., “a” and/or “an” should be interpreted to mean “at least one”or “one or more”); the same holds true for the use of definite articlesused to introduce claim recitations. In addition, even if a specificnumber of an introduced claim recitation is explicitly recited, suchrecitation should be interpreted to mean at least the recited number(e.g., the bare recitation of “two recitations,” without othermodifiers, means at least two recitations, or two or more recitations).Furthermore, in those instances where a convention analogous to “atleast one of A, B, and C, etc.” is used, in general such a constructionis intended in the sense one having skill in the art would understandthe convention (e.g., “a system having at least one of A, B, and C”would include but not be limited to systems that have A alone, B alone,C alone, A and B together, A and C together, B and C together, and/or A,B, and C together, etc.). In those instances where a conventionanalogous to “at least one of A, B, or C, etc.” is used, in general sucha construction is intended in the sense one having skill in the artwould understand the convention (e.g.,“ a system having at least one ofA, B, or C” would include but not be limited to systems that have Aalone, B alone, C alone, A and B together, A and C together, B and Ctogether, and/or A, B, and C together, etc.). It may be furtherunderstood by those within the art that virtually any disjunctive wordand/or phrase presenting two or more alternative terms, whether in thedescription, claims, or drawings, should be understood to contemplatethe possibilities of including one of the terms, either of the terms, orboth terms. For example, the phrase “A or B” may be understood toinclude the possibilities of “A” or “B” or “A and B.”
